The interview mostly involved behavioral questions. This was the pre interview to see if they liked you, then would decide to bring you to their office for the offer. Unfortunately I did not get an offer, though I did not have enough money for a suit and my contacts tell me this might have been part of it. They are pretty selective so it would have been important for me to not make a bad impression like this. So answer truthfully and try not to do something to make them say no to you.
